GPS and Navigation Products
CRS has developed several anti-jam receivers using multiple (2 to 7) antenna elements for civilian and military users. Many of these are presented at different conferences.
The Ultra Tightly Coupled Receiver architecture provides jamming immunity to about 60 dB and can be used against certain types of jammers.
A high performance jammer simulator is available (similar to GPS simulators), that can simulate 24 or more waveforms with extreme precision and with dynamic range up to 140 dB. The jammer simulators can be synchronized with the GNSS simulators.
A novel interference/jammer locator has been developed and availble as a COTS product. It has 52 antenna elements in a 3-D hemispherical configuration and provides localization to within 1 degree.
The GNSS simulators can be used as effective spoofers and various configurations can be provided to validated users and receiver testers.
An add-on module with 4 antenna elements is available for anti-jamming and anti-spoofing operation. This small unit can be used with a handheld GPS receiver.
The signal analysis, signal recording tools, and systems provide useful arsenal against NAVWAR.
